Yesterday, we told you that Katherine Heigl would remain a cast member of Grey’s Anatomy. Now we have a clue as to what she might be facing. According to the Hollywood Reporter, Izzie’s dead fiance, Denny Duquette, will be making some sort of guest appearance next season.

This wouldn’t be the first time Jeffrey Dean Morgan has returned to the series. He appeared in the show’s third year, though only in Meredith’s mind.

Could this be the “unbelievable story line” Stephen McPherson was referring to? Will Heigl be offed and then walk off into the light with her love? Find out when Grey’s returns on September 25.
